Producer prices outran consumer prices in September, and October's report is the test

US producer prices rose 1.3% in September, the largest monthly increase since March 2022, while consumer prices rose 0.6%, according to the Bureau of Labor Statistics (BLS). The gap, and the producer report due on November 13, are the open question in the data that reached the Federal Reserve before its December meeting.

Gasoline rose twice as much for producers as for consumers

The BLS said the producer price index for final demand, which measures prices received by domestic producers, increased 1.3% in September on a seasonally adjusted basis, after 0.5% in August and 0.2% in July. On an unadjusted basis the index climbed 6.3% for the 12 months ended in September, the largest 12-month increase since 6.4% in December 2022.

Goods drove it. Final demand goods prices rose 2.6%, the largest increase since the BLS first calculated the data in December 2009, and over 80% of that rise is attributable to energy, which jumped 10.8%. Half of the goods increase can be traced to gasoline, which jumped 20.3% at the producer level, the BLS said.

Consumers saw a smaller version of the same shock. The consumer price index for all urban consumers (CPI-U) increased 0.6% in September, and its October release shows gasoline up 9.1% and energy up 5.2% that month. Gasoline therefore rose about 2.2 times as much in the producer index as in the consumer index in September (computed: 20.3 divided by 9.1). The two indexes cover different baskets and are not meant to match one for one, so the ratio shows the size of the gap, not a pass-through rate.

October's consumer report showed energy fading and core unchanged

The CPI-U increased 0.4% in October after 0.6% in September, the BLS said. Energy rose 0.7% after the 5.2% September increase, and gasoline rose 1.0% after 9.1%. Food rose 0.5%, and shelter rose 0.3%.

The index for all items less food and energy, known as core, rose 0.3% in October, as it did in September and August. Over the four months from July to October the headline index compounded to a 1.5% increase and core to 1.1% (computed from the monthly changes of 0.1%, 0.4%, 0.6% and 0.4%, and 0.2%, 0.3%, 0.3% and 0.3%). The BLS did not collect survey data for October 2025 because of a lapse in appropriations, so it cannot publish 12-month percent changes for October 2026 for indexes where October 2025 data are unavailable.

What the producer data say beyond energy

Outside gasoline, the September producer report shows price increases in several places. Final demand less foods, energy and trade services, a narrower measure that removes the most volatile parts, rose 0.5% in September after 0.3% in August, and 5.0% over the 12 months, according to the BLS.

Services rose 0.8%, the largest rise since a 0.8% advance in April. Nearly half of that increase came from a 1.4% rise in margins for final demand trade services, which measure what wholesalers and retailers earn on goods rather than the cost of the goods. Margins for machinery and vehicle wholesaling advanced 3.9%, and the index for transportation and warehousing services advanced 3.4%. Margins for automotive fuels and lubricants retailing dropped 30.3%, the BLS said.

The producer data do not show whether those margins will reach consumer prices or be absorbed by businesses. The consumer report puts the shelter index, the largest part of the basket, at 0.3% in October, which the BLS said accounted for over thirty percent of the monthly all-items increase, so shelter alone does not explain the 0.4% rise. The consumer report shows core prices at 0.3% a month for three months, a steady pace that has not yet accelerated. The BLS releases do not say why margins widened.

The dates that will test the gap between the two indexes

Two data points are scheduled before the Fed's next decision. The BLS is scheduled to publish October producer prices on November 13 at 8:30 a.m. ET, according to its release schedule. The Federal Open Market Committee meets on December 8-9, according to the Fed's calendar.

The producer index rose 2.0% over July, August and September combined, against 1.1% for consumer prices over the same three months (computed from the monthly changes above). If October's producer report shows energy easing as the consumer report did, the two measures would be closer together. If it shows further rises outside energy, the September gap would look less like a one-month fuel event.

FinanceInTime has reported on both reports as they came out, including the October consumer price report and the September gasoline jump.

We would treat the producer margins as the figure to watch, not the energy spike

We think the September producer report is the more important of the two inflation reports because it shows pressure that the consumer data have not yet absorbed. Energy explains most of the goods increase, and energy can reverse; the margins in services and the 0.5% rise in the narrow producer measure are harder to dismiss. The opportunity is that consumer core prices have held at 0.3% a month despite that pressure, which may mean businesses are absorbing part of it, although the data do not show that. The threat is that absorption has limits.

We expect the October producer report on November 13 to matter more for the Fed's December decision than a single consumer reading, if the narrow measure again rises 0.5% or more. We would change our view if that measure slows below the 0.3% of August, or if margins in trade services fall back. This is a forecast with conditions, not a certainty.
